Esophageal cancer (EC) takes, all over the world, 9th place in the structure of new incidents of malignant tumors, amounting to 572034 registered cases and 6th place in the structure of mortality rate, taking 508585 lives annually. According to statistical data, EC develops much more often in men than in women (70% of new cases have developed in men), and people over 70 make up about 40% of the total number of cases, with a peak incidence occurring at the age of 50-60 years. However, these indicators vary by geographic region. So, for example, the highest incidence is found in East Asia, eastern and southern Africa (8.1-23.6‱), while the lowest rate belongs to central America. The aim of the research was to study the dynamics of changes in the incidence trends in the Republic of Uzbekistan over the past 20 years.


A meta-analysis of the detection of mortality of esophageal cancer (EC) for all patients with the verified diagnosis was performed. For the period from 2000 - 2019, 18129 patients were identified in the Uzbekistan and the average incidence of EC was 2.8 per 100 thousand of the population. Of these 8283 (45.7%) were treated at the clinic of NCC, in particular, 1174 (14.2%) patients were operated.


The analysis revealed that in 2000, in 0,4% and 18,2% of cases, patients had I - II stage disease, in 64,5% of cases – III, and in 18,2% of cases – IV clinical stage, in 2009, 0,5% and 22,8% of cases, patients had I - II stage disease, in 54,4% of cases – III, and in 16,4% of cases - IV clinical stage, and in 2019, 3,3% and 33,7% of cases patients had I – II stage disease, in 44,5% of cases - III, and in 12,5% of cases - IV clinical stage.


A relative decrease in the mortality rate over the study period was also revealed: from 2.7% in 2000 to 1.8% in 2019. There has been a decrease in the mortality trend - 2000, 2009 and 2019, 2.2, 1.7 and 1.1, respectively. At the same time, 5-year survival was relatively stable and varied in the range of 12.1% - 27.3%. The largest number of patients was identified in the clinical stage III of the disease and ranged from 42.2 to 67%, respectively.
